Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed January 29, 1921. Serial No. 440,919.

To all H'ZZU) it may con-cam Be it known that I. S'rsrrrm' E. Boomxrrr, citizen of Hungary. residing at Hampton, in the county of Hunterdon and State of New Jersey. have invented certain new and useful Improvements in Evaporator-Heating-Unit- Removing Attachments, of which the following is a specification.

My invention relates to evaporators of the type that are used on shipboard, for the distillation of salt water or other water having scale forming impurities, and known as the multi-coil type. Such an evaporator comprises generally, a chamber for the water to be evaporated, upper and lower manifolds for the heating fluid and a series of coils of tubing connected to the said manifolds.

One of the objects of the invention is to provide in a device of this character, a construction permitting removal of the evaporator coils which will cut the necessary floor space for the evaporator to the minimum. and which construction will not be exposed to the corroding influences of the salt water or its vapor.

Another objectof the invention is to provide means for locking the evaporator coils against movement, after they have been removed from the evaporator shell. in order to avoid accidents. which may occur at sea due to the rolling movement of the ship.

it-h these and other objects in view. my invention consists of certain novel and peculiar features of construction and combination of parts as hereinafter described and particularly pointed out in the claims, and in order that the same may be more fully understood. reference is to be had to the accompanying drawings in which,

Figure 1 is a front elevation of the evaporator.

Fig. 2 is a vertical transverse section of Fig. 1.

Fig. 3 is a horizontal section on the line 33 of Fig. 1, with the evaporator coils in withdrawn locked position.

Fig. 4 is a view of a locking bar.

Referring to the drawings for a more co1nplete disclosure of the invention, 1 is the shell of the evaporator provided with a door 2 to which are connected the manifolds 3 and 4. carrying in turn the heating coils 5. The door is secured to the shell in closed position by the bolts 6, and handles 7 are secured to the door for manipulating the coil unit.

For moving the evaporator coil unit? and out of the shell and for supporting it in removed position, I provide a structure consisting of a steel pipe 8 welded into the shell of the evaporator through the center thereof. Secured to the evaporator shell adjacent the tube Sare brackets 9 carrying a roller 10. Riveted to the door 2. whichcarries the complete heating coil unit, is the suspension bar 11 carrying at its inner end the roller 12. the said bar with its roller being adapted to reciprocate and be guided in the tube 8. For locking the suspension bar 11 against longitudinal movement when in extended position, there is provided a locking pin 21 which passes through alined apertures in the angles 9 and through an aperture 22 in the bar 11. Secured to the evaporator shell are angles 13 and secured to the evaporator coil unit are similar angles 14. When the coil unit is withdrawn and in extended position, locking bars 15 are inserted in holes in the angle plates to lock the coil unit against movement. such as would occur due to the rolling of a ship at sea.

In operation. if it is desired to withdraw the heating coil unit from the shell, the nuts are first removed from the bolts 6. By pulling on the handles 7, the unit is withdrawn :1 sufiicient distance to permit inserting the locking pin 21 in the aperture 22 and the locking bars 15 in the holes in the angles 13 and 14. The total weight of the unit is suspended on the bar 11 and rollers 10 and 12. By this arrangement, the rollers confine the movement of the bar 11 to a positive straight motion. which is highly desirable when the unitis to be replaced.

The construction here provided is advantageous because it does away with the external rollers of prior devices which roll on the floor and the floor space is accordingly cut to the minimum. The rollers being cased in a tubing passing through the shell, are entirely outside of it, and by not coming in contact with the salt water or its vapors, corrosion and caking of the rollers is avoided.

From the above description, it will be apparent that I have produced a device of the character described. which possesses all the features enumerated as desirable, and while I have illustrated and described the preferred form of the invention, it will be understood that I reserve the right to all changes falling within the spirit and scope of the appended chime;

Therefore what I claim as new and desire to secure by Letters Patent is:

1. An evaporator comprising a shell, a removable heating unit therefor, a tube carried by the shell, means connected to the heating unit and extending into the tube for supporting the heating unit when removed from the shell.

2. An evaporator comprising 'a'shell, a removable heating unit therefor, a tube carried by the shell, means connected to the heating unit and extending into. the tube for supporting the heating unit when removed from the shell, and means for locking the heating unit against movement when so removed.

3. An evaporator comprising ashell, a removable heating unit therefor, a tube extending into the shell, a supporting bar conneoted t0 the heating unit and extending into the tube and adapted to reciprocate therein. a v

4. An evaporator comprising a shell, a removable heating unit therefor, a horizontal tube extending intocthe shell above the heating unit, a supporting bar adapted to reciprocate in the tube and from which the heating unit is suspended.

5. An evaporator comprising a shell, a removable heating unit therefor, a horizontal tube extending diametrically of the shell above the heating unit, a supporting bar adapted to reciprocate in the tube and from which the heating unit is suspended.

6. An evaporator comprising a shell, a removable heating unit therefor, a horizontal tube extending diametrically of the shell above the heating unit, a supporting bar adapted to reciprocate the tube and from which the heating unit is suspended, a roller carried by supporting bar and engaging the tube and a roller carried by the shell and engaging the supporting bare U 7. An evaporator comprising a shell, a removable heating unit therefor, means for supporting'the heating unit when removed from the shell and means for locking the heatingunit against movement when so removed.
